Abstract

Seventeen enzyme loci have been assayed for electrophoretically detectable variation in a population of the marine bivalve Scrobicularia plana. Mean heterozygosity is 0.120 +/- 0.033. In a comparison involving thirteen enzymes there is a significant correlation between heterozygosity in S. plana and Mytilus edulis and a suggestion of lower mean heterozygosity in S. plana. These findings are discussed in relation to current theories concerning the selective significance of protein variation.

摘要

已对海洋双壳贝类扁平蚬群体中的17个酶位点进行检测，以寻找电泳可检测的变异。平均杂合度为0.120±0.033。在一项涉及13种酶的比较中，扁平蚬和紫贻贝的杂合度之间存在显著相关性，并且有迹象表明扁平蚬的平均杂合度较低。结合当前有关蛋白质变异选择意义的理论对这些发现进行了讨论。
